What Customers Are Saying
Customers praise this product for effectively sealing leaks on roofs, pipes, bathtubs, and outdoor fixtures, with many highlighting its flexibility and ability to bond to wet or dry surfaces. Most find it easy to apply with a putty knife and appreciate its quick drying time. However, a substantial portion report the paste arriving partially or fully hardened in the container, with some finding half or more of the product unusable. Despite this recurring quality concern, most customers consider it a reliable, versatile repair solution when the product arrives in usable condition.

A great product but needs better packaging.
Would Not RecommendWe have used FLEX on so many things around the house. We needed this to seal some tile but when we opened the can and it was dry. We could not even dig into it to get the stuff out. We returned it and opened several cans and they were all dried up. Needless to say we did not buy any.
Great Seal!
Would RecommendVery easy to use. Sealed as it was advertised.
Use caution,
Used once on pipe dripping, didn't hold. Kept can closed per directions. Next use most of can had set up
Very pricey, used it before
Would RecommendPerforms as described

It’s thick
Would RecommendWorks as advertised
Not what I expected for the job I purchased it for
Would RecommendI didn't realize that this product would be so hard to apply smoothly, or that I could not sand it after it dried. For my project, it was not suitable. Make sure you evaluate it before purchasing. It does appear to be a quality product, but know what you're getting before purchase.
5/10
It does the job, but the application was rough.
Easy to apply!
Would RecommendI had never used Flex Paste before and had need for something like its application instructions called for: waterproof, fast drying and strong. I had a cedar covered steel gazebo that had rotted under the cedar facia; big fist size spaces. Flex Paste filled in those spaces easily and quickly then dried into a strong mass and provided a solid, waterproof base now covered with new aromatic cedar facia. Perfect repair, stronger than when new!
Great product
